instead of cellfun what should we us

function compare_cases(country1,names,days,avg_days,dailycases)
IndexC = strcmpi(names,country1);
 [row,col] = find(not(cellfun('isempty',IndexC)))
 dailydata= dailycases(row,:);
bar(days(1:end-1),dailydata);
end

the error is coming like this in command window

 
>>  compare_cases("China",names,days,430,dailycases)
Error using cellfun
cellfun works only on cells.

Error in compare_cases (line 4)
 [row,col] =
 find(not(cellfun('isempty',IndexC)))

You can simply omit this line:

IndexC = strcmpi(names,country1);  % This replies a Logical vector
% [row,col] = find(not(cellfun('isempty',IndexC)))
dailydata= dailycases(IndexC,:);   % Use logical vector as index
